New HTML and Text widgets not saving content

[galbaras]

Existing text widgets can be adjusted, but new text and Custom HTML widgets are not saved, just cleared.

error_log shows the following PHP warnings, which are likely related:

[03-Aug-2017 02:25:31 UTC] PHP Warning: array_merge(): Argument #2 is not an array in /home/ronitbaras/public_html/wp-includes/default-widgets.php on line 117
[03-Aug-2017 02:25:31 UTC] PHP Warning: array_merge(): Argument #1 is not an array in /home/ronitbaras/public_html/wp-includes/default-widgets.php on line 124

The respective code was added in 4.8.1, which makes this even more likely to be the cause.

I've tested with and without setting the title. I've also tested restoring a deleted text widget, and it works OK, so this is probably related to how 4.8.1 creates new widget instances.

@galbaras Hi, did you see Jetpack 5.2 had a bug related to this? It was fixed in 5.2.1: ​https://jetpack.com/2017/08/02/jetpack-5-2-1-fixes-a-sidebar-widget-bug/

If you have Jetpack and you upgrade to 5.2.1, does that fix the issue?

Yay, that did it! Thank you so much.
